Research Interests:
Our work is focused on synthesis of novel pigments, chromophores, photoluminescent and electroluminescent materials as well as investigation of optical properties of materials capable of changes in color and luminescence for various real-life applications. More specifically we develop photonic materials and devices in two main areas: supramolecular materials for molecular sensing and materials that can be used in fabrication of OLEDs.
In the first area of research, we synthesize new supramolecular materials with interesting photonic and/or conductor properties. These polymeric materials are designed to change their photophysical or electrical properties as a result of association with other materials and species. As a part of this research we prepare new conjugated and/or semiconducting polymers with backbone-integrated receptors that are known to bind and sense biologically important materials such as anions, nucleotide phosphates and nucleotide-phosphonate based virostatics. Additionally, we are exploring self-assembled organometallic dendrimers capable of vectorial energy transfer, which is used to relay the information about the presence of various analyte.
The second main research area in the group is oriented toward the design and synthesis of new chromophores for applications in flat displays and development of OLED materials. Here we focus on synthesis of electroluminescent coordination polymers.
